San Francisco International Airport station is a Bay Area Rapid Transit (BART) reversal station on the Antioch–SFO/Millbrae line located inside the San Francisco International Airport, also known as SFO or SFIA.

The station is located on the departures level of the International Terminal, next to Parking Garage G. There are two entrances and exits – one adjacent to the grand foyer off the north side of the International Terminal; and the other is a level up at the Garage G/BART AirTrain station.

The station is a terminus station. Trains enter from an elevated wye from the west side of Highway 101. There are three tracks and corresponding bay platforms. BART traffic to and from SFO has not been as high as originally anticipated, so only two of the three tracks are currently used in regular service, with the third sometimes being used for storage.

Wind Portal[edit]

Wind Portal is the 2003 artwork by Sebastopol artist Ned Kahn on the surface of the cylindrical opening in the floor separating the BART station from AirTrain. Passengers transferring between the two rail services ride escalators or walk on stairs through the opening, which measures 124 inches (3,100 mm) high with a 16-foot (4.9 m) radius. The artwork consists of 200,000 stainless steel disks, each 1 inch (25 mm) in diameter and individually hung so they respond to air currents induced by train traffic.[2][3] John King, urban art critic for the San Francisco Chronicle, praised it, saying it was "[m]esmerizing ... an ever-changing silver shimmer ... indefinable movements reacting to distant winds as well as the whoosh of trains. The experience is hard to predict; there's a sense of anticipation."[4]

Service history[edit]

Service at this station began on June 22, 2003.[5] Originally, there was a purple line for a shuttle service connecting SFO directly to Millbrae from 2003 to 2004.[6] The shuttle trains usually had 5 cars and ran every 20 minutes. On February 9, 2004, BART eliminated direct service between the SFO station and Millbrae (except for a few trips scheduled during the first and last hour of service each day).

Passengers traveling between SFO and Millbrae formerly had to make a timed transfer at San Bruno station.[7] As of September 2012, direct service between the SFO station and Millbrae is active after 9pm on weekdays, and all day on weekends and holidays. Passengers traveling between SFO and Millbrae still need to make a timed transfer at San Bruno during all other operating hours.[8]

When it first opened, ridership was 50% below the projected 6,500 passenger exits per day.[9] During its first decade of service, ridership remained well below initial projections,[10] but has nearly doubled between 2003 and 2015.

Ridership reached a record of 6,788 average weekday exits during the fiscal year ending June 30, 2016.[1] In 2013, BART celebrated ten years of service to SFO and 30 million trips delivered.[6]
